I recently used GarageBand to record our church choir performing. Trouble is, because I recorded all the songs at one time, GarageBand treats it as one very long song. How do I separate each song that the choir sang so that the CD I burn has each individual song on a separate track, like on a commercial CD?

You can do this in GarageBand by placing the playhead between the first and second songs and pressing Cmd-T to split the track. Then click the Cycle button next to the Play button. A yellow bar will appear at the top of the timeline, starting at the beginning of the timeline. Drag the right side of the yellow bar to where you created the split. Now choose Share > Export Song To Disk. Repeat these steps for each song – moving the yellow bar to the beginning of the song and then stretching it to the end.
Alternatively, consider saving the GarageBand track as a single AIFF track and then opening that single track in a different application that handles this kind of thing with greater aplomb. To do that, choose Share > Export Song To Disk. Make sure the Compress option is not enabled and save the track to your desktop.
Download a copy of the free, open-source Audacity audio editor (audacity.sourceforge.net). Launch Audacity and choose Project > Import Audio (Cmd-I). Navigate to the track you saved from GarageBand and click Open. The track will open in Audacity’s timeline.
Click the Selection tool (represented by the I-beam icon) in the top-left corner of the Audacity window and click at the very beginning of the track. Choose Project > Add Label At Selection (Cmd-B) to create a label (properly called a marker) at that point. Move to where the next break between tracks occurs and, with the Selection tool still active, click at this point. Add another label. Continue doing this until you’ve marked all the breaks.
Choose File > Export Multiple. In the Export Multiple window that appears, make sure that the Split Files Based On Labels option is enabled. Choose a location for saving your files, and click the Export button. If asked for an audio format, choose WAV, as this creates audio files at their original fidelity. Audacity will now split your long track into separate songs based on where you placed the labels. You can now import those tracks to iTunes and burn them to disc.
